Elusive Mexican 925 makers mark

[vincec44]

Please help. I have tried every method of identifying this mark, looked in every book available, searched the internet to no avail. Any help would be greatly appreciated. Attached are two photos, one of the front and one of the back. On the back photo there are two marks, one on the left "925" and one on the lower right "P" or a combination of letters. Taking a shot in the dark and assuming the mark is Mexican, but not 100% sure. Anyway, thanks in advance for any help. Vince
